Somewhere along the way, you told me in a PM that a corner weld is easiest to grind. That stuck and where applicable, I leverage it. When a panel face is involved though, yea sometimes it is best to go around the corner just a bit. I enjoyed making the sketch.
You mentioned being a little suprised by how much is left to do on the 41... just remember your own elephant reference. It is also handy for a guy who gets jobs that are a year apiece or more.
You'll do fine once you figure out what exactly to do, and any "help" I can offer is all yours in exchange for those valuable nuggets of wisdom. If I ever shuck paint on the GP, you'll see how I really just skipped all the bodyman work. I wasn't one yet but woohoo boy that paint job!
